The Powerplant

• The Yamaha VXS is powered by a 1.8 liter high output Yamaha Marine Engine. This 1812cc engine, which is purpose-built for the marine environment, is the largest displacement engine ever installed in a personal watercraft. It is also the only engine in the high-performance, four-stroke category optimized to run on the least expensive Regular Unleaded fuel.
• Electronic Fuel Injection (EFI): Throttle position sensor (TPS), intake air pressure and air temperature sensors supply the optimum air/fuel mixture. The results are a smooth, high power output with low fuel consumption and low exhaust emissions.
• Specially Designed, One-piece Cylinder and Crankcase Assembly: Provides tremendous engine rigidity that's lighter and stiffer than two-piece designs.
• Slant Detection Switch : Electronic switch stops engine and oil pumps immediately if watercraft becomes overturned, protecting motor from unwanted water ingestion.
• High Volume Intake Box: With water repellent air filter and flame arrestors.
• SAWS (Scavenger Assist Wet Sump): Equipped with a high-performance, compact gas-liquid separator, this engine uses Yamaha's unique ultra compact lubrication system and oil pan structure.
• Corrosion Protection System: Sacrificial zinc anodes protect the engine from harmful galvanic corrosion. Stainless steel fasteners (nuts, bolts, hardware) provide a long service life. Cylinders, cases and heads are all treated with a durable oxide coating to form a barrier between corrosion and expensive engine parts.
• Electronically Controlled, Variable Ignition Timing: For exact ignition advance control at all throttle positions and RPMs.
• Direct Ignition: For more efficient combustion.

• The Jet Pump Propulsion System

• The Yamaha VXS’s 155mm hyper-flow jet pump propulsion system with three-blade stainless steel impeller : Designed to maximize water flow for high performanceThe VXS’s pump configuration provides excellent hook-up and smooth acceleration.
• Stainless Steel Impeller Housing Liner: For high durability, the liner maintains accurate clearance tolerances between the impeller and the housing.
• High Flow Intake Duct and Grate: The dynamic shape of these items directs water flow into the pump for better thrust, performance and hook up.
• Pumps are Manufactured with YDC30: A combination of zinc and copper alloys, developed by Yamaha marine engineers, that offers excellent corrosion protection.

• The NanoXcel Hull and Deck

• The Yamaha VXS features the world’s first hulls and decks manufactured through the use of cutting edge nanotechnology. Yamaha’s NanoXcel ultra-lightweight, high strength material reduces the weight of the hull, deck and liner by 25% and provides performance gains in acceleration, fuel reduction, top speed and handling. Additionally, the NanoXcel material offers a shinier, gem-like finish which reduces surface tension on the water, providing a more nimble, responsive ride.
• Progressive, Stepped Draft V-Hull with Integrated Bow Spray Guard : Provides excellent maneuverability, handling and comfort.
• Performance Sponson Design: Provides added straight-line comfort and an improved two-up and three-up riding experience.

• Additional Features

• Multi-function Electronic Information Center: Provides the operator a quick read on speed, RPM, fuel level, low fuel warning, low oil pressure warning, overheat warning, hour meter, check engine light with self diagnostic function.
• Industry's First Remote Controlled Transmitter: With the touch of a button on Yamaha's innovative remote-controlled transmitter, you can activate and deactivate the VXS’s digital security system and Low RPM Mode from up to 30 feet away.
• Low RPM Mode™: The personal watercraft industry’s first fuel saving feature, Low RPM can reduce fuel consumption by up to 26% based on average annual use.
• Yamaha Security System: This security system that can be activated with the touch of a button ensures that no one starts the VXS without your permission.
• Dual Concave Mirrors: Automotive style and convenience.
• 15 Gallons of Total Storage: Includes a large bow storage locker and glove box.
• Comfortable One-piece Seat: Ergonomically-designed and contoured for added support. The extra-long seat is easily removed for quick access to the engine compartment.
• Extra Large Boarding Platform: Provides a stable platform for reboarding.
• Finger Throttle Lever: Provides added comfort while reducing hand fatigue.
• Yamaha's Trademarked Visibility Spout®: A waterspout from the rear of the craft that improves the watercraft's conspicuity.
